Pull back the carpeting in the driver's footwell. In the Passat (which is a mechanical near-twin to the A4) there is a relay setup under there that, if worn out or damaged, will cause the car to go haywire. Check it out, decontaminate and resolder it if you can, try to dry and clean it, and if not, replace it.
